One post below tried to say that Egyptians are not Arabs. He is correct in that most 'Arabs' in the Middle East are not necessarily directly descended from the invading armies of the peninsula.

The Berbers who fiercely kept their own language do not identify as Arabs: Most Egyptians do, even if they are Egyptian first and Arab second.
